If they post a screenshot now, a few things could happen:1. People will love the way it looks, and will complain about how long it's taking to be released.2. People will hate the way it looks, and will complain about that AND how long it's taking to be released.3. Things will change between now and the release, people will have been complaining about how long it's taking to be released, and will then have to begin complaining about how things changed.

If they don't post a screenshot now:1. People will complain about how long it's taking to be released.
